DETAILED DESCRIPTION

Embodiments of the present invention are characterized by a method forproviding a keyword-based user interface in an electronic device. Forexample, the user interface of the present invention displays one ormore layers of keyword menu for the user to choose from and thus guidesthe user to a function which the user wants to perform.

According to embodiments of the present invention, keywords are chosenfrom a text corpus artificially or by a machine, carry naturallinguistic meanings or semantic meanings comprehensible to the user, andare for use in referring to extensive information embodied in the textcorpus. Accordingly, in an embodiment of the present invention, dailymeanings of keywords apply to the usage context of an electronic deviceso that the user can operate the electronic device with the userinterface of the present invention according to the user's generalunderstanding of the keywords.

Furthermore, embodiments of the present invention are furthercharacterized in that keywords, which vary from user to user, serve asthe user interface for operating the electronic device and evenexecuting the same function.

Unlike the user interface (such as a “keyword menu”) of the presentinvention, a conventional electronic device is equipped with a“function-based” user interface (such as a function menu or a treedirectory), such that the user can browse the user interface only bymeans of a name or icon attributed to a function and configured by aprogram developer. However, the name or icon of the function isconfigured by the program developer from the perspective thereof andthus seldom bears any semantic meaning comprehensible to the user,thereby being susceptible to misinterpretation.

For example, users who seldom use Microsoft's Windows operating systemare unlikely to get the meanings the program developer wants to instillinto names or icons of “my computer” or “network neighborhood” displayedon the user interface and spotted by the users, nor can the usersdiscern whether the names or icons are relevant to any function theusers currently want to execute. In this regard, conventional userinterfaces lack ease of use, because conventional user interfacedevelopers gave no consideration to the difference in the background orcomprehension skills between the users. In view of this, an embodimentof the present invention is characterized in that the user interfacededicated to a user is produced in accordance with a keywordcomprehensible to the user.

Furthermore, the advantage of a keyword-based user interface is that:the user understands the semantic meaning of each keyword or theinformation to be referred to by each keyword, and thus the userinterface can be designed according to corresponding relationships ofthe semantic meanings of the keywords or the information to be referredto by the keywords in order for the user interface to have a treestructure or a hierarchical structure for assisting the user inbrowsing, such that the user can readily understand the context of thewhole structure and browse it. For example, the user can understandreadily that four keywords, namely “spring”, “summer”, “fall”, “winter”,belong to the same layer in the tree structure, and that “Christmas”belongs to the next layer and is linked to the keyword “winter”.

Conceivably, with conventional user interfaces providing the name of afunction only, it is difficult for the user to gain insight into therelation between the layers of a tree structure or hierarchicalstructure only by the name of a function in the absence of any otherauxiliary tool.

In another aspect, comprehension of the same keyword varies from user touser, and thus an embodiment of the present invention is characterizedin that the user interface dedicated to a user is produced in accordancewith the user's understanding of a keyword. Referring to the examplementioned earlier, the keyword “Christmas” is linked to the keyword“winter” at the preceding layer as far as the user interface of a userlocated in the Northern Hemisphere is concerned, whereas the keyword“Christmas” is linked to the keyword “summer” at the preceding layer asfar as the user interface of a user located in the Southern Hemisphereis concerned. Hence, when users are going to the keyword “Christmas”, aselected path leading thereto on the tree structure of the userinterface depends on user's understanding of the keyword and thus variesfrom user to user.

By contrast, the tree structure of the conventional user interface isdesigned in accordance with the name or icon of a function; as a result,not only are users forced to “learn” the meaning of every name on thefunction menu, but all the users are provided with the same path leadingto a specific position of the tree structure of the user interface.

FIG. 1 shows a block diagram of an electronic device 10 according to anembodiment of the present invention. The electronic device 10 comprisesa display unit 102, a processor 104, a memory 106, a communicationmodule 108, and a data input module 110.

The electronic device 10 comes in the form of a typical notebookcomputer or a portable information device similar thereto. Preferably,the electronic device 10 is a mobile phone. For details of the basicstructure of the electronic device 10, make reference to products ofApple Inc., such as iPhone™.

For example, the processor 104 is a central processing unit (CPU)produced by ARM and adapted for use with a mobile device. The memory 106is a flash memory which stores computer-executable instructions of anapplication AP and is accessible by the processor 104 to execute thecomputer-executable instructions.

The application AP comprises a keyword-based user interface illustratedwith FIG. 2 through FIG. 4 e and described below.

The communication module 108 effectuates networking by means of UMTS,GSM, or Wi-Fi and connects with one or more servers 20. The data inputmodule 110 can be integrated with the display screen 102 to form a touchscreen whereby a user creates data or enters instructions.

In this exemplary instance, the memory 106 is equipped with targetdatabase DB_(T) and user profile database DB_(U); however, it is alsofeasible for target database DB_(T) and user profile database DB_(U) tobe disposed at the servers 20, such that the processor 104 of theelectronic device 10 can access target database DB_(T) and user profiledatabase DB_(U) at the servers 20 through the communication module 108.

In another exemplary instance not shown, the electronic device 10 comesin the form of a mainframe or a high-level workstation with robustprocessing capability and storing capability, such as IBM's System X,Blade Center or eServer, and provides a webpage interface whereby anyuser connected to the Internet can access the electronic device 10 bymeans of an electronic device or portable device in wide use.

The required network can also come in a connection of any type,including a wide area network (WAN) or a local area network (LAN) withstatic IP, or a temporary connection to the Internet through an Internetservice provider (ISP), whether by cable connection or by wirelessconnection. Persons skilled in the art are able to understand that thenetwork can also have other hardware and software elements (such as anadditional computer system, a router, or a firewall) not shown in theaccompanying drawings.

FIG. 2 is a flow chart of a method according to an embodiment of thepresent invention. Referring to the electronic device 10 shown in FIG.1, the method for providing a keyword-based user interface for anapplication AP according to an embodiment of the present invention isdescribed below.

Block 200: determining at least one function to be provided by anapplication AP. Block 200 is similar to its conventional counterpartregarding the existing way of developing applications. In thisembodiment, the application AP is an application pertaining to personalhealth care guide, and its purpose is to provide users with daily healthcare information on an electronic device by means of text or multimedia,for example, displaying multimedia messages MSG1, MSG2 “recommendeddaily caloric intake for males aged 30 is X kcal” and “jogging iseffective in alleviating disease Y” (as shown in FIG. 3).

The aforesaid application, whose nutrition tips or fitness tips can beillustrated with products available on Apple's App Store, does not havethe user interface of the present invention. As a result, although theaforesaid application provides sufficient functionality (abundant healthcare information), the health care information is not readily accessibleto users through an existing user interface.

Furthermore, in an embodiment of the present invention, thefunctionality of the application AP is not restricted to displayingmultimedia messages but includes controlling components (such as acamera unit) mounted on the electronic device or controlling the otherapplications (for example, controlling a voice communication program todial the phone number of a specific subject).

Block 202: in an aspect of the present invention, a keyword-based userinterface is provided; hence, this block entails determining startingkeywords for use in starting each function of the application AP.

The starting keywords are either set by a program developer, or arechosen or created from a target database DB_(T). After the startingkeywords have been determined, the starting keywords are associated withthe function. The target database DB_(T) is either created by theprogram developer, or is created by following any advice provided by adomain expert. In a preferred embodiment, target database DB_(T)comprises specific contents and information pertaining to a function(such as multimedia messages) provided by the application AP, whereintarget database DB_(T) automatically parses the contents and informationof the function beforehand to thereby create multiple keywords forfunctioning directly as the starting keywords or a candidate listthereof to be screened by a developer, thereby allowing the startingkeywords to be automatically associated with the function.

For example, after the multimedia message MSG1 “recommended dailycaloric intake for males aged 30 is X kcal” has been parsed, itselements, namely “aged 30”, “males”, and “calorie”, are automaticallytreated as the keywords for starting the display of the multimediamessage MSG1. After the multimedia message MSG2 “jogging is effective inalleviating disease Y” has been parsed, its elements, namely “disease Y”and “jogging”, are automatically treated as the keywords for startingthe display of the multimedia message MSG2.

In an exemplary instance not shown, if a function provided by theapplication AP is “dialing 24-hour enquiry hotline automatically forhospital's advice on disease Z”, the function will be parsed in a mannerto treat “disease Z” or “enquiry hotline” automatically as the keywordfor starting the dialing function.

Block 204: the starting keywords in block 202 are directly associatedwith the function of the application AP, and thus their semanticmeanings are not only specific or narrow but are also unlikely to beused in the user's daily vocabulary. To enable the user to browse theuser interface easily, it is preferable to introduce some linkingkeywords for providing background-specific or guide-like keywords whichcarry extensive semantic meanings or are in wide use in the user's dailylife to thereby assist the user in associating the introduced linkingkeywords with the starting keywords in block 202.

In an embodiment, the linking keywords are selected or created fromtarget database DB_(T), for example, in block 202, unselected startingkeywords serve as the linking keywords. Alternatively, the linkingkeywords can be set by the user. However, in a preferred embodiment, thelinking keywords are selected or created from profile database DB_(U),wherein profile database DB_(U) stores the user's personal data relatedto age, gender, nationality, educational background, medical record, andweb browsing history or stores personal profiles available on socialnetworking services (such as Facebook or Twitter).

Understandably, linking keywords created from profile database DB_(U)must have the same context as the user's daily life does, and thus theirsemantic meanings are understood by the user quickly and correctly.Furthermore, profile database DB_(U) parses personal data automaticallyto thereby create multiple keywords which serve directly as the linkingkeyword or a candidate list thereof. For example, “health”, “exercise”,and “diet” serve as the linking keywords, as soon as the user's webbrowsing history indicates that a health information-related Website hasa high click through rate (CTR).

If the user wants to include the other users' personal data in profiledatabase DB_(U) for reference, it is preferable to screen the otherusers' personal data by a similarity algorithm beforehand to ensure thatthe other users will be peers to the user, that is, the other usersmanifest considerable similarity with the user in a given dimension, andthus the linking keywords created from profile database DB_(U) by meansof the peers' personal data can be provided to the user for meaningfulreference.

Techniques of calculating the similarity of multiple users by asimilarity algorithm to determine peers are not only well known topersons skilled in the art but are also disclosed in Taiwan PatentApplication No. 101127574 filed by the applicant of this patentapplication, and thus the techniques are not described in detail hereinfor the sake of brevity.

In another embodiment, if the user's personal profile available on asocial networking service indicates that the user has intimateinteraction or close linking relationship with a member Q on anothersocial networking service, it will also be feasible to treat “member Q”as a linking keyword. Hence, it is further determined, according to therecord of interaction between the user and member Q on the socialnetworking service, that both the user and member Q are highlyinterested in diet-related topics, and thus “diet” can also be treatedas a linking keyword.

In another aspect, if member Q agrees to share his or her web browsinghistory or personal data with the user, member Q will be deemed theaforesaid peer to thereby create a linking keyword for use by the useron the electronic device 10, or it will even be feasible to directlytreat any keyword predetermined by member Q (or another peer) as theuser's own linking keyword.

In the aforesaid embodiment, target database DB_(T) in block 202 andprofile database DB_(U) in block 204 are two separate databases.However, in another embodiment, target database DB_(T) and profiledatabase DB_(U) are integrated to become a single database. Methods ofgenerating keywords automatically from a given database (target databaseDB_(T) or profile database DB_(U)) are not only well known to personsskilled in the art but are also disclosed in U.S. Patent ApplicationPublication 2005/0086219 and U.S. Pat. No. 7,546,280, and thus themethods are not described in detail herein for the sake of brevity.

This embodiment of the present invention does not require that blocks200-204 have a specific execution sequence, and more particularly, doesnot specify the sequence of determination of functions, startingkeywords, and linking keywords, and thus the determination of functions,starting keywords, and linking keywords can take place separately, andit is even feasible to determine starting keywords and linking keywordsfirst and then determine functions.

Block 206: creating by the program developer a keyword tree KT with ahierarchical structure from starting keywords determined in block 202and linking keywords determined in block 204 according to their semanticmeanings, as shown in FIG. 3. Given adequate text corpus samples (suchas the archives of a news Website), a computer program can analyze andidentify the general semantic meaning of each keyword and therebyautomatically create the keyword tree KT.

In this embodiment, the keyword tree KT has layers L1, L2, L3 in atop-to-bottom direction. The linking keywords “health” and “member Q”are placed in the top layer L1. The linking keywords “exercise” and“diet” are placed in the intermediate layer L2. The starting keywords“nutrition”, “calorie” and “jogging” are placed in the bottom layer L3.

The keyword tree KT shown in FIG. 3 is illustrative of the presentinvention and thus can represent a portion of the keyword tree of thepresent invention, because the embodiments of the present invention arenot restrictive of the size of the keyword tree.

Furthermore, whether a keyword is a “linking keywords” or a “startingkeywords” may depend on specific functions of the application AP; hence,referring to FIG. 3, the “linking keywords” located at layers L1, L2 canserve as the “starting keywords” of the other functions. Similarly, the“starting keywords” located at layer L3 in FIG. 3 can serve as the“linking keywords” of the other functions.

In another aspect, there is at least one path between any two keywordson the keyword tree in an embodiment of the present invention. Referringto FIG. 3, keywords “health” and “nutrition” are either directly linkedup, or linked via keyword “diet” or another keyword (not shown). Hence,when compared with conventional user interfaces characterized by a“functionality-based” hierarchical menu or tree directory, the presentinvention provides a keyword tree which features high flexibility andhigh popularity among users.

Block 208: providing the keyword tree KT on the electronic device 10 forthe user to browse. For example, the keyword tree KT comes in the formof a hierarchical menu or tree directory (but the present invention isnot limited thereto, for more examples, see FIG. 4 a through FIG. 4 e),such that the user can select the “linking keywords” at layers L1, L2 bymeans of the hierarchical menu and then select the “starting keywords”at layer L3 to thereby start a function associated with the startingkeywords (see block 200).

Block 210: as mentioned earlier, the keyword tree KT comes in the formof a hierarchical menu or tree directory. For related details of ahierarchical menu or tree directory, make reference to function-basedhierarchical menus and tree directories of the user interface ofMicrosoft's Windows operating system. Take a hierarchical menu as anexample, it enables the user to select and trigger any item on the menuand thereby display a next-layer menu or start a specific function.

The hierarchical menu in an embodiment of the present invention iskeyword-based (rather than “function-based” according to the prior art)and thus keywords can serve as items on the menu; hence, in block 210,optionally, the user is allowed to set a criterion for selecting andtriggering a specific keyword automatically.

Unlike the prior art which discloses function-based menus, the presentinvention, in an embodiment thereof, adopts a keyword-based menu inwhich keywords serving as items on the menu, and thus the user isallowed to set keywords of any hierarchical structure (rather than setthe “starting keywords” of the next layer only). Furthermore, in anembodiment of the present invention, the configuration of keywords isbased on semantic meanings thereof and thus is so simple that the userdoes not even need to know the positions of the keywords on the keywordtree, nor does the user need to understand the framework of the keywordtree.

Referring to FIG. 3, the user may configure that keyword “health” oflayer L1 is automatically selected and triggered and keyword menu (whichhas thereon items presented in the form of keywords “diet” and keyword“exercise”) of layer L2 is automatically unfolded as soon as theelectronic device 10 determines that the current time or place matches adefault value or the electronic device 10 receives a specific signal(such as a specific phone number of an incoming call or a RF signalcarrying a specific message). Likewise, the user may further set anothercriterion for automatically selecting and triggering keyword “exercise”or “diet” of layer L2 to thereby unfold the keyword menu of layer L3. Inanother embodiment, if the electronic device 10 has a sound inputfunction (carried out by a microphone, for example), the user can setthe criterion for automatically selecting and triggering keyword“health” of layer L1 to a received sound, say, the sound produced by theuser's pronunciation of the word “health” or the sound produced by theuser's exhalation toward a microphone.

In another embodiment, if the electronic device 10 is capable of sensinglight (by means of a light sensor, for example), the user can set thecriterion for automatically selecting and triggering keyword “health” oflayer L1 to a light ray perceived. For example, the user may set thecriterion to the detection that the light intensity of a light raysensed by a light sensor is lower than a default value (for example, asa result of the user's hiding the light sensor by hand, or when thelight sensor-equipped side of the electronic device 10 is turned awayfrom a light source). However, the aforesaid technical feature is notessential for the present invention.

Block 220: after providing the keyword tree KT for serving as the userinterface, the application AP can be configured with a given period oftime (such as a day, a week, or a month), so as to obtain the user'sbehavior pattern toward the keyword tree KT during the given period oftime, for example, the frequency of selecting a specific keyword orspecific path on the keyword tree KT, the most common time and place ofa specific keyword or specific path, or a remark entered by the user(with a button “like” or “dislike”) and directed to a specific keyword.

By a value-assigning data processing process, each keyword or path onthe keyword tree KT is assigned a value indicative of the user'sbehavior pattern to thereby allow comparison, statistical analysis, orevaluation to be performed. The present invention is not restrictive tothe aforesaid way of data processing whereby a value is assigned toindicate a behavior pattern.

Block 222: after a value has been assigned to each keyword or path onthe keyword tree KT to indicate the user's behavior pattern, if thekeyword tree KT is presented on the electronic device 10 byvisualization and layer by layer, it will be feasible to adjust how akeyword is presented according to the behavior pattern value of thekeyword or adjust how each keyword on a path is presented on the userinterface according to the behavior pattern value of the path. By thisoperation, it is feasible to predict keywords which are likely to appealto a user and highlight the displayed keywords according to the user'spast behavior pattern.

The aforesaid adjustment is carried out, for example, by changing thefont size, font, position, and color of a keyword presented on the userinterface as well as the sequence in which the keyword and the otherkeywords are presented in the same layer. The extent of the aforesaidadjustment depends on either the difference between the behavior patternvalue of the keyword (or path) and a preset reference value, or thedifference between the behavior pattern value of the keyword (or path)and the behavior pattern value of another equivalent keyword (or path).

Referring to FIG. 3, for example, if the behavior pattern value(determined in block 220) of keyword “health” of layer L1 is higher thanthat (determined in block 220) of keyword “member Q” in the same layer,block 222 can entail presenting keyword “health” in a font larger thankeyword “member Q”

For example, if the behavior pattern value (determined in block 220) ofpath 1 (from keyword “health” of layer L1 to keyword “diet” of layer L2)is higher than that (determined in block 220) of path 2 (from keyword“health” of layer L1 to keyword “exercise” of layer L2), block 222 canentail presenting keyword “diet” of layer L2 on path 1 with a higherpriority or in a more conspicuous manner than keyword “exercise” oflayer L2 on path 2. The main difference between the two aforesaidexemplary instances is described below. The latter exemplary instancegives considerations to a path, that is, keywords in the upper layer,wherein the result of the calculation of a behavior pattern value variesfrom path to path (for example, switching to keyword “member Q” of layerL1 but keeping the same keywords in layer L2 (i.e., using keyword “diet”and keyword “exercise”), whereas visual presentation of the keywords islikely to vary accordingly. By contrast, the former exemplary instancegives no considerations to keywords in the upper layer.

Moreover, in addition to adjusting how a keyword is visually presentedaccording to a behavior pattern value, the behavior pattern value isfurther for use in adjusting the position of a keyword on the keywordtree KT. For example, if the behavior pattern value (determined in block220) of keyword “nutrition” of layer L3 is higher than that (determinedin block 220) of keyword “calorie” of layer L3 and the differencetherebetween is larger than a predetermined value, block 222 can entailupgrading keyword “nutrition” from layer L3 to layer L2 and omittinglinking keyword (i.e., keyword “diet”) of layer L2 from its upward pathsuch that keyword “nutrition” is linked directly to linking keyword(i.e., keyword “health”) of layer L1, thereby allowing the user tobrowse much more easily.

In addition to a conventional hierarchical menu or tree directory, FIGS.4 a-4 e illustrate another way of providing the keyword tree KT (asshown in FIG. 3) for the user to browse.

FIG. 4 a shows that the keyword tree KT has not yet been presented or ishidden, thereby showing that the electronic device 10 has a backgroundBG (such as wallpaper). Keywords at a specific layer on the keyword treeKT are displayed, in response to an operation performed by the user onthe electronic device 10, for example, the user's pressing a specificphysical button (not shown), or the detection by the electronic device10 of an event (say, the detection that the electronic device 10 isbeing shaken in a specific manner by the user or has been overturned bythe user, the detection of sound input, or the detection of a specificsignal by the electronic device 10) configured by the user.

Referring to FIG. 4 b, which shows keywords “exercise” and “diet” oflayer L2, wherein keywords “exercise” and “diet” are presented in theform of icons G1, G2, respectively, and presented in the background BGby animation.

In an embodiment, the user watches icons G1, G2 moving in the backgroundBG. Furthermore, icons G1, G2 for keywords “exercise” and “diet” havetheir respective unique visually perceivable features in terms of size,shape, color, and transparency. In the embodiment illustrated with FIG.4 b, icons G1, G2 for keywords “exercise” and “diet” have differentbubbly peripheries, wherein bubbly icons G1, G2 rise slowly from thebottom border of the background BG like real bubbles do in response toan operation (such as shaking, overturning, and sound input) performedby the user on the electronic device 10. For example, the user selectsand triggers keyword “diet” by pressing bubbly icon G2, and thenkeywords (not shown) of the bottom layer L3 are displayed in a waysimilar to that of icons G1, G2.

In an exemplary instance not shown, bubbly icons G1, G2 rise, and theybegin to move horizontally or downward as soon as their periphery comesinto contact with the bottom border of the background BG. Bubbly iconsG1, G2 are not only adjustable in shape and size but also capable ofsimulating real bubbles.

As with real bubbles, icons G1, G2 each preferably have a transparency(whether equal or unequal) whereby the background BG is partiallyexposed.

Optionally, in response to an operation (such as a click) performed bythe user, bubbly icons G1, G2 either stop moving to be quiescentlypresented in the background BG or disappear from the background BG.Alternatively, the user may configure that, when a predetermined periodof time has lapsed, bubbly icons G1, G2 either stop moving to bequiescently presented in the background BG or disappear from thebackground BG automatically. In another aspect, in response to anoperation (such as a drag) performed by the user, the user either movesbubbly icons G1, G2 to an intended position in the background BG andpresents bubbly icons G1, G2 quiescently, or throws bubbly icons G1, G2out of the background BG to make bubbly icons G1, G2 disappear from thebackground BG and makes a “dislike” remark by means of the aforesaidthrow-out (see block 220 of FIG. 2), for example.

In another aspect, in an embodiment illustrated with FIG. 4 c, inresponse to an operation (such as a drag) performed by the user, theuser moves bubbly icons G1, G2 to an interface of an operating system oranother application of the electronic device 10, such that functions orinformation directly or indirectly associated with bubbly icons G1, G2(for example, through their downward hierarchical structure) areaccessible by the operating system or the other application. Forexample, the user drags bubbly icons G1, G2 to an attachment selectioninterface (shown in FIG. 4 c) of an email program to thereby treat anyinformation or file associated with bubbly icons G1, G2 as an attachmentto an email.

Referring to FIG. 4 d, two electronic devices 10 operate synchronouslyas configured by the user, and thus the two electronic devices 10 eitherdisplay at least one keyword (i.e., bubbly icons G1, G2) of a specificlayer in the keyword tree KT simultaneously according to asynchronization signal between the two electronic devices 10 (forexample, by Wi-Fi or Bluetooth), or create their respective keywordtrees KT anew according to information carried by the synchronizationsignal to thereby achieve the effect of sharing or exchanging keywords.

In an embodiment illustrated with FIG. 4 e, which is similar to anembodiment illustrated with FIG. 4 b, in response to an operationperformed by the user on the electronic device 10, keywords of aspecific layer on the keyword tree KT are displayed. However, theembodiment of FIG. 4 e is different from the embodiment of FIG. 4 b inthat, in the embodiment of FIG. 4 e, only one keyword (such as keyword“exercise” G1 of layer L2) is displayed in each instance, and thenanother keyword (such as keyword “diet” G2 of layer L2) in the samelayer is displayed in response to another operation (for example,shaking the electronic device 10) performed by the user on theelectronic device 10, with the original keyword (i.e., keyword“exercise” G1) being displayed or hidden no more, wherein keyword iconsG1, G2 are displayed in a preset sequence or in a sequence determined inaccordance with the keyword behavior pattern mentioned in blocks 220,222 illustrated with FIG. 2.

In this embodiment, keywords are not necessarily displayed in the formof icons. For example, it is also feasible for the keywords to bepresented dynamically by means of a marquee at the bottom of thebackground BG without involving use of icons. Conversely, if the iconsdepicted in FIGS. 4 b-4 e are also employed to start a specificfunction, the icons will not necessarily be implemented in conjunctionwith the method depicted in FIG. 2 or FIG. 3.
